2015 Map of Illinois City

About this map

The Mississippi River creates a complex boundary between Muscatine County, Iowa, and Rock Island County, Illinois, defined by a network of islands and sloughs. Small riverside and upland settlements like Fairport and Illinois City anchor the local geography, connected by rural routes such as Loud Thunder Rd and Old Highway Rd. The Iowa side features the distinct communities of New Era and Sweetland Center, surrounded by family-named burial grounds including Harker Cem and Krell Cem. The river's path is marked by a series of significant landforms, from Geneva Island and Hershey Island to Andalusia Island, while the braided waters of Wyoming Slough and Scisco Chute illustrate the dynamic floodplain. This 2015 survey provides a modern record of the enduring agricultural and river-based character of these border townships.
